Snarl is a global notification system. Snarl works in a similar way to the balloon-style tooltips that appear from time to time in the system tray, however it doesn't take the keyboard focus away when displaying a notification. Multiple notifications can be displayed at once and you can also change the appearance of the notifications.

To use Snarl, simply launch it from the Start Menu. The first time it runs it will test how quickly blended images can be drawn - this test should take less than 5 seconds on most computers - and then display a notification confirming it started okay. After this Snarl will sleep quietly in the background until an application sends it a notification.
